NAME

       LqrImageType - carver objects image type (colour model) specification

DESCRIPTION

       The LqrCarver objects use knowledge about the image type they're working on in order to compute correctly some quantities (e.g. the
       brightness) for the automatic feature detection. Image types are set automatically by the constructors, but they can also be specified
       manually using quantities of the type LqrImageType, which is an enum which can take these values:

       o   LQR_GREY_IMAGE.RE

	   o   LQR_GREYA_IMAGE.RE

	       o   LQR_RGB_IMAGE.RE

		   o   LQR_RGBA_IMAGE.RE

		       o   LQR_CMY_IMAGE.RE

			   o   LQR_CMYK_IMAGE.RE

			       o   LQR_CMYKA_IMAGE.RE

				   o   LQR_CUSTOM_IMAGE.RE

				   Use the function lqr_carver_set_image_type(3) to set the image type of a carver, and the function
				   lqr_carver_get_image_type(3) to read it out.

NAME

       lqr_carver_set_alpha_channel - sets the alpha channel index in a LqrCarver object

SYNOPSIS

       #include <lqr.h>

       LqrRetVal lqr_carver_set_alpha_channel(LqrCarver * carver, gint channel_index);

DESCRIPTION

       The function lqr_carver_set_alpha_channel sets the alpha channel index of the image stored in the LqrCarver pointed to by carver to
       channel_index (between 0 and channels - 1, where channels is the number of colour channels of the carver).

       Use a negative value for cahnnel_index to specify that no alpha channel is present.

       If the specified channel coincides with the current value of the black channel, the black channel is unset.

       Calling this function sets the image time of the carver to LQR_CUSTOM_IMAGE.

RETURN VALUE

       The return value follows the Liquid Rescale library signalling system.
